Wiberg et al. prepared an TV-silyl substituted iminosilane by means of an N2/NaCl and -LiCl elimination. None of the intermediate products was isolated. The iminosilane was formed in the reaction of azido-di-f-butylchlorosilane and tri-t-butylsilylsodium in dibutyl ether at -78°C.13-16... 

Polyfluoro-/f-sultones 3 isomerize in the presence of nucleophilic catalysts to polyfluorinaied a-fluorosulfonyl acyl fluorides 4.45 47 The nucleophilic catalysts include triethylamine,45 ammonia,48 dioxane,49,50 dibutyl ether,49,50 and alkali metal fluorides.46 The reaction has been carried out thermally and in the presence of liquid hydrogen fluoride.50... 

The C-F bonds in l,l-difluoro-l,2-diphenylcthane (5) are resistant to several reducing agents the substrate is recovered unchanged after exposure to 2% sodium amalgam in ethanol or to zinc dust in refluxing ethanol and refluxing acetic acid. It is only partially converted into a mixture of 1,2-diphenylethane and ( )-l,2-diphenylethene with lithium aluminum hydride in refluxing dibutyl ether. On the other hand, catalytic reduction over palladium catalyst is completely successful.74... 

Lundgren et al. (1999) evaluated the field exposures of painters to a low-VOC and a conventional water-based paints in Sweden. They found that exposures to TVOC, 1,2-propylene glycol, acetaldehyde and ammonia were 3-12 times lower for the low-VOC paint, but exposure to formaldehyde (160-180 pgm ) was 3-4 times higher. Brown (2000) reported that emissions from four Australian VOC-free paints included typical aromatic VOCs, dibutyl ether, ethylene glycol butyl ether, diethylene glycol butyl ether and Texanol , though at order of magnitude reduced levels c.f. conventional water-based paints, as well as formaldehyde and benzaldehyde. 

Arylcyclopropanes can also be obtained in reasonable yields by heating mixtures of aryl triphenylphosphoranylidenehydrazones 9 and chalcones 10 in a solvent (usually dibutyl ether).Presumably, the reaction does not involve a free carbene instead dipolar addition of the in situ generated diazo compound to the C-C double bond of the enone takes place. The resulting 4,5-dihydro-3/f-pyrazole is thermally unstable and extrudes nitrogen, thus affording 2,3-diaryl-l-benzoylcyclopropanes 11. °...

Dibutylcarbitol (di[ethyleneglycol]-dibutyl ether, bis[2-butoxethyl]-ether [112-73-2] M 218.3, b 125-130 /0.1mm, d f 0.883, n 1.424. Dibutylcarbitol is freed from peroxides by slow passage through a colunm of activated alumina. The eluate is then shaken with Na2C03 (to remove any remaining acidic impurities), washed with water, and stored with CaCl2 in a dark bottle [Tuck J Chem Soc 3202 1957], [Beilstein 1IV 2395.]... 

Some authors have used the solvent mixture IV, Table 109 a, which contains ammonia [33, 50, 106, 157]. Agreement between the hi /-values is adequate, as seen from Table 109b. In two of the publications mentioned [33,106], the use of a pyridine-containing mixture. III (Table 109a) and the acid solvent, n-butanol-n-dibutyl ether-acetic acid (40 + 50 -f 10), was quoted. Reference may be made also to neutral solvents (Table 109 a and [25]) which have been employed in the chromatography of narcotic bases. Other more or less modified solvents can be found in the articles quoted and in [41].
